Product Description:

The BTV20.3PA-28B-33C-D-FW operator terminal is produced by Bosch Rexroth Indramat and belongs to the BTV20 Machine Operator Panels series. Acting as a human-machine interface inside automated cells, it combines a graphical display, embedded electronics, and fixed machine keys in one housing. This arrangement lets operators start cycles, adjust parameters, and view status information without opening the drive cabinet.

This panel is supplied with a base hardware profile that includes a minimum 3 GB HDD and a 300 MHz CPU, so local applications can run without external storage or processing add-ons. Volatile memory totals 128 MB RAM, which supports active recipe data, screen handling, and runtime variables during operation. The unit accepts AC 115 to 230 V mains power, and its internal power conversion supports 50 to 60 Hz sources commonly found in industrial facilities. The front membrane includes 16 machine function keys that are scanned by the onboard microcontroller for single-stroke or latched commands, and a standard alphanumeric keyboard is provided for text entry during setup or operation. An internal watchdog continuously monitors temperature and voltage so that abnormal conditions can be signaled before data loss occurs.

The housing uses Design 3, so the mounting holes, connector layout, and cooling clearances match third-generation BTV cutouts used on compatible panels. A 3.5-inch, 1.44 MB disk drive is installed for small file transfers when network access is unavailable or not used on the machine. The unit is classified as IPC, which indicates that it runs an embedded operating system and can host soft PLC tasks alongside visualization software on the same terminal. This model is also part of Product Line 20, which aligns it with related line-20 cabling and diagnostic tools within the platform.
